wasm: move qwasmwindowclientarea content to qwasmwindow
This allows us to keep all event handlers in one place. Move event handler registration to registerEventHandlers(), which is called from the QWasmWindow constructor. Change-Id: I31f22d6eb876b92bb15d4a140e0569f0288a5915 Reviewed-by: Morten Johan Sørvig <morten.sorvig@qt.io>
